Intermentancy issues caused by flapping port router downstream

I'm in chesapeake virginia  the Cox infrastructure is stretched very thin here. In our area, we have multiple outages weekly that last for more than a few hours and then daily outages.That last between 5 to thirty minutes we have packet loss at 55% on 100 pings to the cox router 68.1.0.242. I believe it could be a faulty s f p or even a issue with a loop fill the arc table either way can this site be upgraded it's on the older side net gear 10+ years old

First, what is your technical background? Are you a tech or someone in that field? Just trying to figure out how to word my response based on your expertise. 

Second, can you show some data? A tracert or pingplotter of the packet loss? Signal levels on your modem? Logs(edit out MAC first)? Last, have you had a technician out yet?

PS. You have normal cable(HFC) internet right? Not fiber?

Network engineer but non familiar with commercial networks

No fiber, I tracert to get the cox router 69.1.0.242 then ping -t to check out the packet loss the outages affects a large area but not the entire area. I'm making an assumption.I think there is a network stack a smaller use to segment the area that is possibly having the issue 

I do have a snip of the loss I dont see a place I can attach it here. Using phone currently 

And no technician out yet

You can either upload it to imgur or use the "insert media" button on the bottom of the post. It will look like a camera.

No I meant showing a full tracert from command prompt or use the pingplotter program(free for 2 weeks) to show where the packet loss is occurring. With PP, you can go to file > share >create sharing page to share the data.  winMTR might work too if you prefer something open source.

Can you answer my other questions?

Also, are the "outages" declared on their outage page or do you just mean times without service? Like are others around you affected?

That IP does not belong to Cox. It belongs to WoW internet. See here. Can you explain?

You want to look at the first and second hop. The first is between you device and router/gateway. The second is between the modem/gateway and the ethernet interface on Cox's CMTS. That should be a 10.x.x.x IP. Make sure you are testing from a wired connection, so either a PC/laptop or a phone using a USB/ethernet adapter.

Last, what model modem/router do you have?

That is a different IP. You posted 68.1.0.242 in OP then 69.1.0.242 in 2nd post.

Again< I suggest posting the entire trace or using pingplotter. If you think it's a Cox issue and don't want to troubleshoot, contact Cox.

I don't see a model # but it's a white rectangle delivered in AUG last year, thank you for that clarification on the IP, I am testing from my PC it was just at the time the internet was to unstable for me to communicate the issue from my PC

You are a network engineer but you use the ISP's gateway? Wow. That's like a race car driver driving a automatic.  Not saying it's causing the problem, but isn't helping and limits what you can do on your network.
